They're typically referred to at 140mm or 170mm magazine bodies. I'm just not sure if the user/purchaser has to cut out the magazine catch in the body, or if you can order them somewhere to be cut out for a particular mag catch design.

The differences between a BHP/CZ/Beretta/XD/etc doublestack metal bodied magazine just aren't that major, and I'm wondering if anyone makes a 140/170 body that can be set up to run in an XD.
